Hello,
I have received a response from the technical team of our institutional repository of scientific papers (named DIAL).
In a nutshell: Due to a high volume of requests from AI language models overloading the DIAL server, access from outside the EU has been temporarily restricted. The IT team is working on a solution to distinguish legitimate (human) traffic from illegitimate traffic, which may be slowed or blocked. A more sustainable fix is expected in the coming weeks. Sorry for the inconvenience.
On a personal note, the increasing impact of LLM training activities is becoming a serious concern for academic projects, as it can compromise the accessibility and reliability of essential research infrastructure. This is not the first time that the Orthanc project is subject to such disrespectful behaviors.
Regards,
Sébastien-
